Package

ABSTRACT

A package for sheets, for example sheet formed information carriers such as CD-sheets, DVD, CDR, CD-RW and so on and including an outer envelope ( 3 ) and an inner envelope ( 4 ) formed separately or in one and a same piece together with the outer envelope, manufactured by carton, paper, plastic, wellpapp or the like which have been folded to constitute a cover protecting the sheets ( 2 ) or the actual sheet at the same time as the inner envelope ( 4 ) supports and partly encloses the sheet ( 2 ), so that from the inside ( 13; 14 ) of the outer envelope ( 3 ) close to its back portion ( 5 ) the inner envelope ( 4 ) extends in a direction forwards and includes at least one open space ( 6 ) delimited laterally by a double fold ( 7 ) on each side, which has a length forwards which extends past the half diameter of the stored sheet ( 2 ).

The present invention refers to a package for sheets for example sheet formed information carrier such as CD-sheets, DVD, CDR, CD-RW and so on and comprising an outer envelope and an inner envelope of carton, paper or plastic, wellpapp or the like formed separately or in one on the same piece together with said outer envelope and cooperating with the same and said envelopes are folded in order to constitute a cover which protects the actual sheet or sheets at the same time as the inner envelope carriers and partly encloses the sheet itself.

On the market there are today several different types of envelopes or packages for sheets for example CD-sheets, which usually are manufactured of a solid plastic material. These packages are weak and can very easy get broken during hard handling. Another drawback with this type of package is that it usually has a thickness which is greater than that thickness which easy can be provided by a package of paper or other sheet formed material. The types of packages which are now on the market and consist of folded carton blanks have the drawback that the CD-sheets easily slide out from the same. There are also such types of packages of carton, which are formed as a book and which furthermore comprise a description of the melodies, which are on the CD-sheet. Also this type of package has that drawback that the CD-sheet itself easily slides out from the package when it has been opened.

The object of the present invention is to provide a new type of package for sheet formed objects of the type mentioned above and where the drawbacks existing with the previously known packages have been eliminated. The characterizing features of the invention are set forth in the following claims.

Thanks to the invention a new type of package for sheet formed objects has been provided, which in excellent way fulfills its purposes. The package itself comprises according to the invention an outer envelope and an inner envelope where said inner envelope has a special formation in order to grip and keep the actual sheet in a special way so that the same can not slide out from the package until the same has been opened. The opening of the package is done in such a way that the same is opened in the same way as a book and first after that the package has been opened about to the half and more the sheet itself can be taken out. The taken out of the sheet is made easy in that the envelope in connection with its opening automatically lifts upwards that space, which contains the sheet when the outer envelope has been opened somewhat over half its opening moment, which means that the sheet is very easy to take out for a user. With other words this means that when the package or envelope, which protects the sheet is closed and half opened, the sheet is kept in its place by a folded claw-formation and when the envelope is opened totally said claw-formation opens, lifts up and exposes said sheet in order to make it easy to grip.

The invention is described closer below by aid of a preferable embodiment example in view of the drawings enclosed, in which

FIG. 1 shows a perspective view of the package according to the invention, in which the same has been opened somewhat and where said sheet has been lifted upwards for its taken out,

FIG. 2 shows a schematic perspective view in a view oblique from above, where the package is in its closed position,

FIG. 3 shows the same view as in FIG. 2 but in a view obliquely from above and where a package has been opened to about the half and where the claw-formation is going to loosen the sheet,

FIG. 4 shows the same view obliquely from above where the package has been opened totally so that the sheet not at all is kept in place by said claw-formation and

FIG. 5 shows a plan view of the blank which is used as inner envelope for cooperation with said outer envelope and for supporting the sheet itself.

As can be seen from the figures a package 1 is illustrated according a preferred embodiment example of the invention intended for sheets 2, for example sheet formed information carriers, which comprise an outer envelope 3 of carton, paper and plastic, wellpapp or similar and an inner envelope 4 which can be manufactured of a similar material as the outer envelope 3 and which has been double folded to constitute a cover for protecting the sheet 2 at the same time as the inner envelope 4 supports and partly encloses the sheet 2 itself. In the example illustrated the inner envelope is manufactured separately and thereafter fixed to the outer envelope 3 but the inner envelope 4 and outer envelope 3 can also be formed separated from each other.

As can be seen from the figures the inner envelope 4 is fixed and formed in such a way relatively the outer envelope 3 that these two envelopes cooperate with each other in storing and taking out of the sheet 2 from the package 1.

From the inner side 13 of the outer envelope 3 close to its back portion 5 the inner envelope 4 extends in a direction forwards and comprises here an open space 6 delimited laterally of a double fold 7 on each side, which has a length forwards from said back portion 5, which extends past the half diameter of the stored sheet 2, so that during the closed position of the package 1 and up to its mainly half opened position or immediately before the half opened position said space 6 has an opening width, which, after the extending forwards of said double fold 7 past the half diameter of the stored sheet 2, is less that of the diameter of the sheet 2, in that said double folds 7 converge in a direction towards each other in order to prevent a sliding out of said sheet 2 out from said space 6 and during the continued opening of said package 1 and up to its totally opened position, said space 6 has an opening width, which is greater than the diameter of the sheet 2 at the same time as the space 6 having a stored sheet 2 is automatically lifted upwards and exposes said sheet 2 and makes it easy to grip.

As is closer illustrated in FIG. 5 said opened space 6 in the inner envelope 4 is constituted by two double folds 7, which consists of two along a crasing line C, in the illustrated example in the form of a double crasing line, foldable and directed towards each other, triangle formed portions 8,9 and said portions 8,9 in turn are via upper and lower crasing lines A and B foldable formed in said inner envelope 4. The upper crasing lines A extend in each triangle formed portion 10, which in turn are foldable and symmetrically connected via crasing lines D by a triangle formed portion 11 delimited forwards in a direction viewed from said back portion 5 of the last mentioned crasing lines D. The crasing lines D are of the same length and the limit two sides of the triangle formed portion 11, said portion along its base side is delimited of a transversitally extending crasing line D. The crasing line E extends in turn into a portion 12, at which a triangle formed portion 11 is foldable provided. The base of the portion 12 consists of a crasing line F, by which a portion 12 via a flap 12 are foldable connected with any of the two insides 13 or 14 of the outer envelope 3 in a short distance from the back portion 5, i.e. the inside of the front or backside. The flap 17 is fixable against the front inside 13 and is intended to extend in a direction towards the back portion 5 or alternatively in an opposite direction in the direction upwards over the front inside 13. The lower crasing lines B of the double fold 7 extend into a portion 15, which via crasing lines G foldably extend into a portion 16, which is fixed to the back inside 14 of outer envelope 3.

In FIG. 5 is thus illustrated how the inner envelope 4 of the package 1 is formed with its crasing lines and portions and from this figure it is specially the portion 11 having the crasing lines D and E, which make or influence the opening and closing of the claw-formation during the cooperation of the inner envelope 4 with said outer envelope 3.
